Ok, so I got my namecoin address by following tutorial on this forum..... Now, how can I manage my future namecoins? Is there any wallet or what? This thing that I downloaded helped me to get my address but how can I/or can I use it as a wallet as well?

Or is there something I should do more, some GUI client like bitcoin or something else to get namecoins?

Note: Im a stratus miner whatever that means
